Well, last night while watching some Direct TV down in the Plex last night, my son and I start hearing some clicking/ticking sounds coming from the left side of the room.

At first I thought it was something coming from the left surround. However, it did it on other channels as well. The first time I walked over to figure out what it was the sound stopped. I was confused...

After a bit it started again, and as I approached the 600, and listened back by the amp side, I could tell it was something in the amp ticking.

I turned off the power and unplugged the AC for a few minutes, and when I plugged it back in and turned it on, it started clicking again. As far as I can tell I'm still getting some bass from the sub and as I turn up the gain I get increased volume.

I can call Axiom, just thought I would see what you guys think; fuse? something else?

I new we shouldn't have started watching Ghost Adventures and Dead Files on SciFi, and communicating with a ghost box. It is basically the clicking sound you hear when first turning on the 600 amp, it just keeps doing it.. I do have a different amp than the current 600v3 has in it.
